Where it fits
Part of Coming next: Product lines in development. Tested code, not yet sold or hosted. Every CAIN-42 product runs behind the same rule: an AI agent's action is checked before it runs (identity, authority, policy, risk), decided as allow, hold for a human, or block, and recorded as signed evidence. Unknown or error never becomes allow.

What E36 claims, and how far each claim goes
- C42-E36-EXCHANGE
TESTED: a governed machine agency exchange implements the lifecycle DISCOVER -> IDENTIFY -> VERIFY -> EVALUATE -> NEGOTIATE -> CONTRACT -> AUTHORIZE -> EXECUTE -> PROVE -> SETTLE -> RATE -> REASSESS -> RENEW_OR_REVOKE over services, contracts, bids and transactions - C42-E36-NOT-AUTHORITY
TESTED: no economic object (identity, passport, contract, bid, reputation, payment, price, receipt) is authority; CONTRACT != AUTHORITY and the deterministic kernel and E8 still decide - C42-E36-DISCOVERY
TESTED: governability-aware discovery never upgrades UNKNOWN to MATCH; the marketplace filters on hard requirements and reports UNKNOWN explicitly - C42-E36-CHAINS
TESTED: a service chain produces identity/authority/contract/capability/execution/proof/settlement proof chains; a subcontractor's authority cannot exceed its parent's - C42-E36-NOT-BANK
TESTED: CAIN is not a bank, custodian or regulator; escrow governs conditions only, units are SYNTHETIC, and no insurance or underwriting exists - C42-E36-BENCH
TESTED: 3340 of 3340 economic/governance scenarios across 64 categories held; 842 of 842 invariants; mutation 15 of 15 - C42-E36-CLEANROOM
TESTED: an independent verifier that imports none of CAIN re-derives the E36 invariants and rejects every crafted forgery - C42-E36-HONEST-SCOPE
TESTED: the exchange is an in-process TESTED library, not a deployed network; CAIN-MSDP is experimental; no customers, market data, revenue or market moat is claimed
Known limits of E36
- An in-process TESTED library; not hosted, not a deployed network. The directory and marketplace are local registries, not a public exchange.
- CAIN is NOT a bank, custodian or financial regulator. Escrow and settlement govern CONDITIONS only; units are SYNTHETIC and there is no payment rail or real money.
- CAIN-MSDP is an experimental CAIN protocol; there is no external adoption and it is not an industry standard.
- A2A/MCP integration is exercised via reference adapters; no external protocol support is claimed.
- Reputation, performance and quality graphs are evidence views built from in-process events; there are no real reviews, customers or market data.
- Dispute and arbitration are machine infrastructure layers; they are not legal advice, not arbitration and not a substitute for courts.
Tested guarantees in this area
Every rule in these niches has its own page with its recorded result.
- Autonomy, control loops & recovery: 407 tested invariants — Agents acting on their own, and how CAIN keeps them in bounds and recovers.
- Transactions, markets & economics: 664 tested invariants — Agents that buy, sell, bid and pay, within limits.
